Australia's size means weather advice for one city rarely applies to another. Here's what to expect, season by season, across our most-requested destinations.
Figures below are typical averages, not forecasts -- always check closer to your travel dates. Remember Australia's seasons are reversed from the Northern Hemisphere: December-February is summer, June-August is winter.
